thanks in advance

Some companies just ask you to send them your ECU, they chip it and send it back the same day they receive it. They also claim this mod cannot be detected by your dealer, 100,000km warranty or 2yrs.

6.2 secs to 100km/h I think that is damn good. Thanks bagu.

I'll start a new thread with info collected about chip tuning the 3.0sd by different companies. Just not to hijack this thread

Just a remark, some tuners offer the measurements on the bench afterwards. Thus they are sure the tuning was done correcly.
I had the problem on my new (4000km) 320d, out of factory she had al little dip in the power graph, the tunner saw this before he perfomed tunning and send my of to my BMW garage. Something with EGR I think... So afterwards, returned to tuner and got my tuning done and validate on the bench.

In regards to your question, I don't think BMW will see the tunning. The ECU containt huge tables of hexadecimal figures defining the different setting for the motormanagement (pressure, spray, timestamp, tubo pressure, opening, pre-opening, pedal status, rpm, ...) at any given position (external temp, air temp, pressure, ...) These are adjusted by the tuners with special software, I don't think BMW can go through these with their diagnose software.

On the other hand, I know that for RR when you get a software update done your tuning will be gone...

Oh, we have send the ECU (together with te engine ) of our Porsche GT3 about 8 times from Belgium to Weissach for engine maintenance, it can handle the road trip. Just be sure to get a certified delivery, ECU is not that cheap.

ajogu,

Any updates on your ECU mod ? Did you push thru with driving to HARTGE factory. What is the model of your X5 diesel ? I drive an 02 X5 3.0d euro.
